Specification of Letters Patent.

.catented July 24:, 1906.

Application filed June 26,1905. Serial Nov 266.961-

To a whom it may concern.-

Be it known that we, SAMUEL ORUMP and GEORGE SAGUE, citizens oftheUnited States, and residents of Poughkeepsie, in the county ofDutchess and State of New York, have invented certain new and usefulImprovements in Machines for Cleaning or Treating Printers Rollers, ofwhich the following is a specification.

The invention relates to improvements in machines for cleaning ortreating printers rollers, such as the inking and distributing rollersof typographic and lithographic presses; and it consists in the novelfeatures and combinations of parts hereinafter described, andparticularly pointed out in the claims.

The object of the invention is to provide a novel machine which willwith certainty and rapidity efiiciently remove the accumulations of ink,paper fiber, and other matter from rinters rollers without injury to thesurfaces of the latter.

In its preferred construction the machine of our invention comprisesnovel means for receiving the ends of the roller-shaft and imparting arapid rotation to the roller and a novel tank containing the solventsolution and carrying along the roller a guide-shoe, a brush, and ascraper, whichfeatures are pivoted and adjustable and set at an obliqueangle to the roller. The tank also contains a special solvent-wheel bywhich the solvent is carried 'up to the roller under treatment. Themachine is preferably equipped with a grainer wheel or disk arranged toengage the surface of lithographic rollers during the process ofcleansing the same.

The invention embraces many novel features of construction, form, andarrangement and will befully understood from the detailed descriptionhereinafter presented, reference being had to the accompanying drawings,in which- Figure 1 is a front elevation of a machine constructed inaccordance with and embodying the invention, a lithographic roller beingshown in position in the machine. Fig. 2 is a vertical transversesection of same on the dotted line 2 2 of Fig. 1 and illustrates moreparticularly the special arrangement of gearing for driving the chuckwhich grips one end of the roller-shaft and also for driving the longscrew-shaft which compels the travel of the solvent-tank and its partsalong the roller under treatment. Fig. 3 is an enlarged front elevationof a portion of the machine and illustrates more especially theV-bearingfor receiving that end of the roller-shaft not held by thechuck shown in Fig. 2. Fig. 4 is a vertical section of same on thedotted line 4 4 of Fig. 3. Fig. 5 is an enlarged rear elevation of aportion of the machine. Fig. 6 is a detached top view of the solventtankand parts directly carried thereby, these parts comprising thesolvent-wheel, guide-shoe, brush, and scraper, and their cooperatingfeatures. Fig. 7 is a front elevation of the guide, brush, and scrapermechanism lifted from the solvent-tank. Fig. 8 is a detached frontelevation of a vertical movable piece of the framing for the mechanismshown in Fig. 7. Fig. 9 is a vertical longitudinal section through thesolvent-tank on the dotted line 9 9 of Fig. 6. Fig. 10 is a transversesection through the solvent-tank on the dotted'line 10 10 of Fig. 6 andviewing the mechanism carried by said tank from the left-hand portion ofFig. 6. Fig. 11 is a detached view of a portion of the inner right-handwall, looking at Fig. 10, of the solvent-tank and illustrates thestirrup or loop fastened thereto by screws for supporting one end of atransverse partition, which is shown in section. Fig. 12 is a transversesectional view through the solvent-tank on the line of the transversepartition 82 therein and viewing the solventwheel from the right-handend of Fig. 6. Fig. 13 is an enlarged vertical transverse sectionthrough a portion of the machine, taken on a line with the right-handend of the solventtank. Fig. 14 is a detached side elevation of theguide-shoe and a portion of its support carried by the solvent-tank.Fig. 15 is a like view of the brush and a portion of its support. Fig.16 is a like view of the scraper and a portion of its support. Fig. 17is an enlarged detached view taken from the front of a portion of themachine and illustrates some of the devices presented in Fig. 5 in theposition they assume when the eccentric 69 is turned vertically intolocking position for connecting the solvent-tank with thescrewshaft.Fig. 18 is a vertical longitudinal section through a portion of same.Fig. 19 is a view corresponding with Fig. 18, but illustrating the meansfor locking the solventtank to the screw-shaft as being released fromthe latter, this being the condition presented in Fig. 5. Fig. 20 is avertical transverse section on the dotted line 20 20 of Fig. 17. Fig. 21is an enlarged front elevation, partly broken away, of thegraining-wheel and means for imparting rotary motion to the same fromthe long screw-shaft which moves the solvent-tank. Fig. 22 is a topview, partly broken away, of same. Fig. 23 is a detached view of aportion of the machine, taken from one end of the roller, andillustrates the graining-wheel and parts for cooperation therewith andFig. 24 is a longitudinal section through the rotary chuck and itssupporting means.

In the drawings, 30 31 designate suitable side frames for the machine,these side frames being connected at their lower ends by a rod 32 and attheir upper portions by rods 33 34 and screw-shaft 35, the latter beingjournaled so as to be capable of rotation in the said-side frames.Extending longitudinally between the side frames 30 31 and supportedtherefrom is provided a vertically-adjustable rod 36, which serves as asupport and guide for the solvent-tank 37, the latter being provided atthe ends of its bottom with lugs 38, Figs. 1, 5, and 13, to encompassthe upper portion of and guide upon said rod 36. The purpose in makingthe rod 36 vertically adjustable is to enable the attendant to adjustthe solvent-tank 37 with respect to and in accordance with the diameterof the roller 39, placed in the machine for treatment. The roller 39 isthe usual typographic or lithographic roller and is illustrated incorrect position for treatment in Fig. 1.

The roller 39 has its shaft supported in V- bearings 40 41, Figs. 1, 3,and 4, which are integral with brackets 42, mounted upon the rods 33 34,the said brackets being formed with sleeves to receive said rods andprovided with set-screws 43, by which said brackets may be secured inany set position. The brackets 42 are adjustable upon the rods 33 34, soas to adapt them for the different len ths of rollers 39. The roller 39has one en of its shaft clamped within a rotary chuck 44, by whichduring the operation of the machine the roller is given a rapidrotation.

The chuck 44 is mounted to rotate at the end of an elongatednon-rotatable sleeve or tube 45 and has connected with it a gearwheel46, by which said chuck is given its rotation. shank of the chuck 45 andis of such length that it may receive a part of the shaft of the roller39 said shaft extending into and through said chuck as far as may benecessary. The means for imparting motion to the gear-wheel 46 andthrough the same to the chuck 44 are illustrated more clearly in Fig. 2,in which it may be seen that the gearwheel 46 receives its motion fromthe power- The sleeve 45 receives the hollow wheel 47 through a train ofgear-wheels 48, 49, 50, and 51, the gear-wheel 48 being on thescrew-shaft 35 and said shaft at its outer end receiving the power wheel47. The power-wheel 47 thus imparts simultaneous motion to thescrew-shaft 35 and chuck 44, the screw-shaft 35 during its rotationserving to move the solvent-tank 37 along the roller 39 and the rotationof the chuck 44 serving to rapidly rotate said roller. The chuck 44 andsleeve 45 are suspended by a link 52 from a hood or frame 53, which ispivotally mounted. upon the rod 33 and is provided with a handle forconvenience in raising and lowering the same. The chuck 44 beingsuspended by the link 52 may be adjusted into true alinement with thelongitudinal center of the roller to be treated during any movement ofthe frame 53 to meet the special diameter of the shaft of the roller orthe convenient application of said shaft to or its removal from thechuck 44. The chuck 44 may with the link 52 be raised or lowered by themovement of the frame 53 without disengaging any of the gear-wheels fromeach other, the gear-wheel 46 simply rolling on the, gear-wheel 51 inmaintaining the position of the chuck on a true vertical line and thegear-wheel 49 simply rolling on the gearwheel 48. The rear portion ofthe frame 53 is connected with-a spring 55, whosetend enoy is tocounterbalance said frame. The gear-wheel 49 is mounted on the rod 33,which serves as a pivot for the frame 53, and the gear-wheels 50 and 51are carried by and housed within the frame 53, while the gearwheel 46 issuspended from the frame 53, and the chuck 44, connected with saidgear-wheel 46, is what we term a floating chuck. The features connectedwith and means for operating the chuck 44 so as to effect the rotationof the roller 39 constitute a part of our invention, and we desire tobroadly claim the same. The power-wheel 47 is a fixed wheel and isemployed in connection with a usual loose-belt wheel 56, Fig. 1, anordinary beltshipper 57 being provided for manipulating the belt. (Notshown.)

The screw-shaft 35 is simply a plain spirally-threaded shaft having onone side a keyway 58, cut through the thread thereof, as shown in Figs.5, 17, 18, 19, 20, and 21, and which keyway is employed solely inconnection with the raining-wheel mechanism hereinafter described.

The solvent-tank 37 will preferably be of cast metal and, as abovedescribed, is mounted upon the rod 36. The rear edge of the tank 37 isformed with a loop or folded arm 59, Figs. 5, 6, 12, and 13, whichpasses upon a sleeve 60, Fig. 17, freely mounted upon the screw-shaft35, the edges of said loop 59 passing between and being held byannularshoulders 61, Fig. 5, formed on said sleeve 60. The sleeve 60 isnotinternally threaded, and hence maybe moved freely uponthe screw-shaft35. When the loop 59 of the solvent-tank 37 is upon the sleeve 60 andengaged by the shoulders 61, the said tank is compelled to follow saidsleeve when the latter is moved by hand along or driven by thescrew-shaft 35. The sleeve 60 is formed'with an integral extension 62,which also is normally free upon the shaft 35, but which is equippedwith a threaded section or block 63, Figs. 5, 17, 18, 19, and 20, whichmay be moved into and out ofengagement with the shaft 35. When the block'63 is in, engagement with the shaft 35, as shown in Figs. 17, 18, and20, the sleeve 60 and solvent-tank 37 will be caused to travel length.-Wise of the shaft 35 during therotation of the latter, and when theblock 63 is elevated clear of the shaft 35, as shown in Figs. 5 and 19,the shaft 35 will not impart its movement to the sleeve 60 andsolvent-tank 37. The extension 62 of the sleeve 60 is formed with avertical bracket 64, whose upper rear portion is formed with a sleeve65, Fig. 20,which guides upon the upper rod 33, the latter also servingto prevent the sleeve 60 and its extension 62'from turning with oraround the screw 35. Upon the upper end of the bracket 64 is formed aplate or table 66, up through which passes a link 67, whose lower end ispivotally secured upon an ear 68, connected with the threaded block 63,and whose upper end passes upwardly through the table or plate 66 andhas pivotally secured to it the eccentric 69, having a handle 70, thiseccentric 69 being utilized in holding the threaded block 63 out ofengagement with the screwshaft 35. When the eccentric 69 is intheposition in which it is shown in Fig. 17, it permits the block 63 toremain in engagement with the screw-shaft 35, and when said eccentric isupon its side, as shown in Fig. 5, it holds the block 63 from engagementwith the screw-shaft 35. The block 63 is normally held in its lowerposition in engagement with the screw-shaft 35 by the spring 29, Figs.5, 17, and 20. There are two ears 68 formed on the block 63, and betweenthese ears and pivotally secured thereto by a pin 71 is a cambar 72, oneend of which is inclined, as shown in Figs. 17, 18, and 19, and theother end of which is secured upon a pin 73, extending through anextension 74 of the bracket 64. The arm 72 is a throw-out arm andnormally is in the position represented in Figs. 17 and 18 during theoperation of the machine; but when during such operation thesolvent-tank 37 shall have reached the end of its line of I travel theinclined end of said arm will enter a slot 75, formed in the right-handbracket 42, Figs. 4 and 5, and be turned upwardly, with the result ofautomatically elevating the threaded block 63 clear of the screw-shaft35 and arresting the solvent-tank 37 without in terfering with thecontinued rotation of the screw-shaft 35. The throw-out arm 72 haspivotally connected with it a rod 76, encompassed by the aforesaidspring 29, as shown in Fig. 17, and extending upwardly through the plateor table 66 and engaging the lower edge of the eccentric 69, as shown inFig. 20, at one side of the pivotal center of the latter, as'shown inFig. 17. When the eccentric 69 is in the position shown in Fig. 17 thespring 29 is holding the threaded block 63 in engagement with thescrew-shaft 35, and when the solvent-tank 37 reaches the end of its lineof travel and the throw-out arm 72 is moved upwardly by entering theslot 75 in the righthand bracket 42 said arm 72 will elevate the block63 from engagement with the shaft 35 and at the same time move the link67 and rod 76 upwardly, whereby the eccentric.69

becomes elevated and falls over upon its side and the spring 29 becomescompressed against the table 66, as shown in Fig. 5, the eccentric thenpreventing the block 63 from, under the action of the spring 29,returning into engagement with the said shaftuntil the operator manuallyrestores the eccentric 69 to the position in which it is shown in Fig.17, and thereby releases the spring 29 to act. When the solvent-tank 37has reached the end of its line of travel and the block 63 has-been elevated from the screw-shaft 35, the roller 39 will be removed from themachine and the operator will slide the sleeve 60 and solventtank 37 totheir initial position at the opposite end of the shaft 35 and then turnthe eccentric 69 upwardly to the position shown in Fig. 17 so as toeffect or permit the connection of the sleeve 60 and its parts with saidshaft. threaded block 63, are adapted to move in vertical guides 77,Fig. 20, secured upon the face of the bracket 64.

The mechanism for supporting and operating the graining-wheel 78 is alsoconnected with the extension 62 of the sleeve 60, so that said wheel andsaid mechanism may travel with the solvent-tank 37, and said wheel andmechanism will be hereinafter described, fol lowing a description of theguide, brush, and scraper carried by the solvent-tank 37.

The mechanism supported with inthe solvent-tank 37 and connected withthe guide 79, brush 80, and scraper 81 are more clearly represented inFigs. 7 to 12, inclusive. VVithin the tank 37 is provided a transversepartition 82, one end-of which is formed with a pin 83, Figs. 6 and 10,which sets within a notch formed in the upper rear edge of the tank 37,while the other end of said partition rests within a stirrup 84, securedagainst the inner face of the front wall of the tank 37, as shown inFigs. 6, 10, and 11, said partition 82 thus being rendered removable.The front end of the partition 82 may also be formed with a pin, asshown in Fig. 6, corresponding with the pin 83 at the rear end of saidpartition, to engage a notch in-the front edge of The ears 68, connectedwith the the tank 37 as an aid to firmly sustaining the partition inposition.

Extending lengthwise of the right-hand portion of the tank 37 and atright angles to the partition 82 is a vertically-movable plate 85, whichis guided in vertical grooves in the partition 82 and in a frame 86,applied to the eft-hand wall of the tank 37. The rearface of the plate85 is shown in Fig. 9, and this plate 85 supports the guide 79, brush80, and scraper 81, the said parts being secured to independent heads186, which rest upon the upper edge of the plate 85 and have pivotalstems 87, which extend downwardly through said plate and may have aturning or ivotal action therein. The stems 87 are centra 1y of theguide, brush, and scraper, and hence these features may have a pivotalaction from their centers, so that they may be placed at the mostdesirable angle to the roller 39 and adjusted in accordance with thevarying diameters of rollers to be treated. The guide 79, brush 80, andscraper-blade 81 are of crescent shape or curved on the arc of a circlewhich is greater than'that of the roller 39 to be treated,whereby saidfeatures may always stand at an oblique angle to the roller subjected totheir action and may be adjusted angularly with respect to the diameterof the roller. The heads 186 may be of any convenient outline, sincethey are intended merely to provide means for receiving the guide,brush, and scraperblade, and these heads are, as shown in Fig. 6,connected by a pivoted link 88, whereby the guide, brush, andscraper-blade are compelled to have corresponding movement and aremaintained at the same angle to the roller 39. The scraper-blade 81 isformed with a frontwardlyprojecting arm 89, carrying a spring-detent 90and forming at its outer end a convenient handle 91 for the use of theoperator in adjusting the angular position of the guide, brush, andscraper-blade.

The plate 85, Figs. 6 and 8, is formed with a frontwardlyeprojecting arm92, having a segmental extension 93, formed with a series of apertures,as shown in Fig. 6, to receive the point of the detent 90, the saidextension 93 eing below the arm 89, connected with the scraper-blade andcoperating therewith in securing the scraper-blade with the brush andthe guide in their adjusted positions. The plate 85 therefore supportsthe guide, brush, and scraper-blade, together with the means foradjusting said parts as to their angular positions with respect to theroller 39. The plate 85 is formed at its opposite end edges withrecesses 94, as shown in Figs. 8, 9, and 10, and into these areprojected the rear ends of the lever-arms 95, which extend rearwardlyfrom a rocking frame 96 and are utilized to raise and lower the plate 85and parts carried thereby, whereby the guide, brush, and scraperblademay be elevated into contact with the roller 39 in accordance with thediameter of the latter and may be conveniently lowered therefrom. Theframe 96 (shown in end elevation in Fig. 10, front elevation in Fig. 7,and top elevation in Fig. 6) is journ'aled in the partition 82 and frame86, and the said frame 96 has a frontwardly-projecting arm 97, whichextends upwardly and forwardly from the tank 35 and carries a rod 98,upon which is placed a counterbalance-weight 99, the arm 97 and weight99, which may be slid upon the rod 98, serving to counterbalance theplate 85 and parts connected therewith or overbalance the same, as maybe desired. The rod 98 also serves as a convenient handle by which theoperator may upon raising or lowering the same depress or elevate theplate 85 and parts carried thereby. The frame 86 is connected by a bar200 with the'partition 82.

Within the tank 37 to the right of the partition 82 is provided asolvent-wheel 100, which during the operation of the machine will feedthe solvent to the roller 39. The wheel 1.00 will preferably be formedof wood and have in and crossing its surface the series of grooves 101,which will be very shallow at the right-hand end of the wheel and deepenthence toward. the left-hand end of the wheel, this arrangement of thegrooves 101 serving to feed the solvent in proper quantity to the roller39 without waste and without the solvent being spattered about. Thedeepening of the grooves 101 toward their inner orlefthand ends isparticularly desirable, in that thereby the pressure of the roller 39 onthe liquid in said grooves will move said liquid inwardly or toward theleft into the tank 37 instead of squirting it outwardly to the rightbeyond the tank 35. The wheel 100 is mounted upona shaft 102, which iscarried at the inner or rear end of an arm 103, pivotally mounted, as at104, and having a frontwardly-proj ecting rod 105, up on which isconfined an adjustable counterbalance-weight 106. The arm 103 is alsoprovided with a stop-finger 201, Fig. 12, which prevents the roller 100from descending unduly into the tank 37.

Upon the side of the partition 82 near the front wall of the tank 37 issecured a bracket or upwardly-extending arm 107, as more clearly shownin Fig. 7, having a' horizontally disposed threaded lug 108, throughwhich passes a stop-screw 109, the latter being adjustable in said lug108 and being adapted to be locked in position by a jamnut 110. Thestop-screw 109 is for use in connection with the graining-wheel and'will be referred to hereinafter.

The operation of the machine as thus far described is as follows: Theroller 39 having been secured in position and the solvent-tank being atthe left-hand end of the screw-shaft 35 and power having been applied tothe beltwheel 47, the roller 39 will be rapidly rotated, preferablymaking about one hundred and thirty rot atic ns per minute, and theattendant will by turning the eccentric 69 to the position shown in Fig.17 allow the throw-out arm 72 and the threaded block 63 to move downwardly to the position shown in Fig. 13, thereby restoring the arm 72into its operative position and bymeans of the block 63 connecting thesolvent-tank 37 with the threaded shaft 35. The shaft 35 having been setin motion by the power applied to the belt wheel 47 will rotate and byreason of its engagement with the block 63 will compel the travel of thesolvent-tank and parts carried thereby along the line of the roller 39.The attendant will see that the solvent-wheel 100 is feeding solvent tothe roller 39 and will also not only angularly adjust the guide, brush,and scraperblade with respect to the roller 39, but see that said partsare in proper vertical adjustment with regard to said roller. Themachine having been set in motion and the parts having been adjusted, ashereinbefore explained, the solvent-tank will travel along the roller 39and the guide 79, and thereafter the brush and scraper-blade followingthe solvent-Wheel will act upon the surface of said roller andthoroughly clean the same. The

solvent-tank 37 will continue its motionalong the threaded shaft 35until the throw out arm 72 enters the recess 75 in the righthand bracket42, Fig. 5, and becomes elevated, and thereby disengages the threadedblock 63 from the threaded shaft 35, the tank 37 then coming to a stopwithout interfering with the continued rotation of the said shaft 35.

The parts above described are all of the parts necessary for cleaningtypographic rollers; but in the case of lithographic rollers when thegraining of the roller is desired a graining-wheel 78 will be made useof; but we do not limit our invention in every instance to theemployment of the graining-wheel.

The guide 79 slants downwardly toward the right, and its upper edge isabout oneeight of an inch below the scraping edge of the blade 81, andhence when the blade 81 is in engagement with the roller 39 the guide 79rides idly slightly below said roller. The guide 79, comes into use whenthe solventtank 37 is at the left-hand side of the machine and is aboutto start on its path below the roller 39. At this time the guide 79,brush 80, and blade 81 will be in an upper position above the line ofthe lower surface of the roller 39 and to the left beyond the left-handend thereof, and under such condition, the screw-shaft 35 being inmotion, the tank 37 will travel toward the right, and the guide 7 9 willstrike against the left-hand end edges of the roller 39 and, beinginclined, will travel down the same and against the-lower surface ofsaid roller, the presence of the roller serving to push the guide 79downwardly, so that said guide may pass below said roller. This downwardmovement of the guide 7 9 results in the corresponding downwardmovementof the brush 80 and blade 81," and hence when the tank 37 hastraveled sufficiently farfor said brush and blade to engage the surfaceof the roller 39 said brush and blade-will be in proper position toengage said. r0ller,'and' thereupon, the blade 3i being slightly higherthan the guide 79, the latterwill travel'clear of the roller, and onlythe brush and blade will engage the latter. The purpose of the guide 79is therefore at the starting of the operation to guide the brush 80 andblade 81 into just the proper position to properly engage the roller 39.In the absence of the guide 79 the attendant would have to exercisespecial care in engaging the blade 81 with the roller 39. Otherwise saidblade might on its first contact with the roller 39 by being too highinjure the same. The brush 80'is a scratch-brush, and it serves to cutup the color and matter on the roller, so that the solvent may readilyengage the same preparatory to the scraping and cleaning action oftheblade81. The guide, brush, and scraper-blade are of crescent-edgeoutline or have concave edges to engage the surface of the roller 39,the curvature of these edges not necessarilydefining a technically trueare of a circle, but having a greater sweep than the circle of theroller, whereby said features are not only rendered effective for rapidwork, but are ren dered adjustable to the varying diametersof rollers tobe treated, the axial adjustmentof the guide, brush, and scraper-bladebeing conveniently permitted and adding greatly to the efficiency andadaptability of the machine. i

The guide, brush, and scraper-blade, or the blade alone, if that only isused, -may be caused to yieldingly engage the roller 39 by thecounterbalancing or overbalancingeifect of the weight 99, and inaddition the operator may while observing the condition of the rollerincrease or decrease the pressure of the blade against thesame by manualforce applied to the handle-rod 98. The solventwheel may also be movedby hand into more or less firm contact with the roller 39, or the weight106 may be utilized for pressing said wheel automatically and with ayielding pressure against said roller. I

The brush 80 is a scratch-brush, and we do not limit the invention toits employment in the position shown in Fig. 6, since a-scratchbrush maybe applied to the roller 39 in various ways, one of which is illustratedin Fig. 12, wherein we illustrate a brush 121 engaging the roller 39 andcarried by a crank-arm 122, connected with the shaft of the solventwheel100. The scratch-brush 80 in the positionshown in Figs. 6 and 9 is veryeffective and represents the preferred construction. The more essentialfeature of the mechanism carried by the tank 37 is thepivotally-mountangle to the roller and be adjusted to meet the varyingdiameters of rollers.

The solvent-tank 37 operates as a carriage for the scraper-blade 81,this tank under the construction illustrated serving not only to supplythe solvent to the roller and carrying the scraper-blade 81, butreceiving the matter removed from the roller.

We do not limit our invention to the fact of causing the tank andscraper-blade to travel along the roller-39, and. we would. regard ourinvention as present in a ma@ chine comprising the obliquescraper-blade. whether the latter traveled along the roller 39 orremained stationary'and the rotating roller traveled along it. Theremust be a relative movement between the roller and the scraper-blade inthe longitudinal direction of the roller, and while we illustrate therotating roller as held in stationary bearings, and the scraper-blade asbeing caused to travel we do not exclude from our inventiona machine inwhich the rotating roller may be caused to travel with relation to theblade 81..

As apreliminary step to the operation of the machine the solvent-tank 37should be vertically adjusted with respect to the diameter of the rollerto be treated, because it is not desired that the solvent-wheel, guide,brush, and scraper-blade should be required to have undue verticaladjustment with respect to the roller, and therefore we support thesolvent-tank 37 upon the rod 36, which is vertically adjustable. When aroller of small diameter is to be treated, the rod 36 and tank 37 willbe adjusted upwardly toward the roller, and when a roller of largerdiameter is to be treated the rod 36 and tank 37 will be correspondinglylowered. WVe do not limit the invention to any specialvertically-adjustable support for the tank 37, but in the presentinstance illustrate the ends of i the rod 36 as provided withgear-wheels 111,

Fig. 1, in engagement with vertical rack-bars 112, secured to the sideframes 30 31, Figs. 1 and 2, said gear-wheels 11 1 being held withinloop-frames 113. Adjacent to the left-hand end of the machine we provideupon the rod 36 a pivoted lever-arm 114, carrying a pivoted pawl 115 inengagement with a portion of the adjacent gear-wheel 111. In rear ofthis gear-wheel 111 we pivotally secure to the frame 30 a toothed bar116, which is pressed by a spring 117 against the said gear-wheel toprevent downward travel of the same, the said bar 116 serving to lockthe gear-wheel against downward movement, and this serving to lock theshaft 36 and tank 37 in such position as may be given to them. The pawl115 has a hook-point which enters between the teeth of the gear-wheel111, and thus when the lever-arm 114, Fig. 2, is pushed downwardly atits outer end the pawl 115 will cause the gear-wheel 111 to travelupwardly upon its rack-bar 112, thus elevating the rod 36 and tank 37,since both ends of the rod 36 move correspondingly, though power isapplied only to one end of said rod. The rod 36 becomes elevated, due toan oscillatory or pumping action of the lever-arm 114, and said rod maybe lowered by simply freeing the pawl 115 from its gear-wheel andpressing the lower end of the toothed bar 116 inwardly clear of saidgearwheel, thus allowing the rod- 36 to descend by gravity.

The loop or folded arm 59 on the tank 37 may in the-vertical adjustmentof said tank move vertically on the sleeve 60 and between the flanges 61thereon without losing its connection therewith. The loop or folded arm59 also permits the tank 37 to be lifted from the machine wheneverdesired.

The guide 79, brush 80, and scraper 81 may also be readily lifted fromthe tank 37 with the partition 82 and frame 86.

We have hereinbefore described the construction and operation of all ofthe features of the machine, except those connected with thegraining-wheel 78, and this wheel 78 will be employed when the rollerunder treatment is a lithographic roller. The Wheel 78 receives itsmotion from the screw-shaft 35 through a series of spiral gear-wheelsand shafts. (More clearly illustrated in Figs. 1, 21, 22, and 23.) Thescrew-shaft35is formed with the keyway 58 and upon this shaft ismounted'a spiral gear-wheel 123, Figs. 5 and 22, which has a featherdisposed within the said keyway 58, so that during the rotation of theshaft 35 the said wheel 123 will be compelled to rotate, but may at thesame time be moved along said shaft under the influence of the sleeve60, which carries the solvent-tank along. The spiral gear-Wheel 123 isheld within a yoke 124, Figs. 5 and 22, which encompasses the shaft 35and is connected by a block 126, Fig. 5, with the extension 62 of thesleeve 60, whereby said yoke 24 is compelled to travel with said sleeve,while in the meantime the spiral gear 123 is rotated by means of theshaft 35. The spiral gear 123 is in mesh with a spiral gear-wheel 126,Figs. 1 and 21, secured at the lower end of a vertical shaft 127,mounted in a vertical sleeve 128, supported from the yoke 124, and uponthe upper end of this shaft 127 is secured a corresponding spiralgear-wheel 129, Fig. 22 which engages a spiral gear-wheel 130, securedupon a horizontal shaft 131, which extends lengthwise of the roller 39and is mounted in a sleeve 132,which by means of an ear 133, Fig. 22, issupported from the verticalsleeve 128. The spiral gear-wheel 130 issecured upon one end portion of the shaft 131, and upon the other endportion of said shaft is secured a IIO spiral gear-wheel 133, which isin mesh with a spiral gear-wheel 134, secured upon the spin dle 135 ofthe graining-wheel 78 which spindle normally stands vertically andextends upwardly through a yoke 136, Fig. 22, which is hung upon theshaft 131 and is bifurcated to straddle the spiral gear-wheel 133, asshown in Fig. 22, while at its outer portion said yoke 136 receivesbetween its upper and lower arms the spiral gear-wheel 134, as shown inFig. 21. Below the yoke 136 is a sleeve 137, through which the spindle135 passes and which affords a substantial hearing for the'same, and thesaid yoke 136 is provided at one side with a handle or arm 138, which isadapted when the machine is in operation to rest upon the vertical screw109, hereinbefore described, as shown in Fig. 23. The position of thescrew 109 regulates the contact of the graining-wheel 78 with the roller39. If the roller 39 should have some raised places on its surface,itwould be desirable to move the screw '109 upwardly, so that the wheel 78might smooth down such raised surfaces or elevations, and thus beprevented from harshly treating the roller. The pur-' pose of the screw.109 is therefore to regulate the relation of the wheel 78 to the roller39, so as to enable the wheel 78 to efficiently perform its duty withrespect to rollers varying in condition. During the rotation of thethreaded shaft 35 to move the solvent-tank 37 and scraper-blade 81 themotion of the tank is communicated to the yoke 124 and parts connectedwith the graining-wheel 78, and the rotation of the screw-shaft 35 iscommunicated to said wheel 7 8 so that it may rotate with its faceagainst the surface of the roller 39. The shaft 35 imparts rotarymovement to the spiral gear-wheel 123, keyed upon it, and this spiralgear-wheel 123 communicates motion through the spiral gearwheel 126 tothe vertical shaft 127 and also to the spiral gear-wheel 129, fastenedupon the upper end of said shaft. The gear-wheel 129 imparts motion tothe spiral gear-wheel 130 and shaft 131, and this shaft carrying thespiral gear-wheel 133 imparts motion through the gear-wheel 134 to thegraining-wheel 78. Thus the machine is adapted for cleaning and graininglithographic rollers, as well as for cleaning typographic rollers.

When it is not desired to use the disk wheel 78, the wheel and itsspindle will be turned upside down upon the shaft 131 the yoke 136operating as the hinge, said yoke being freely hung upon said shaft 131.The wheel 78 may be used technically as a means for grindin down roughsurfaces on the roller 39 or or graining said roller.
